How Much Fiber Should I Eat Per Day?

As a whole, fiber delivers a lot of health benefits:

• supports weight loss
• reduces cholesterol and blood sugar levels
• lowers risk of cardiovascular diseases such as stroke, heart disease, and more
• lowers risk of diabetes
• increases digestive and bowel health
• fuels healthy gut bacteria
• may lower risk of colorectal and breast cancer

In general, “dietary fiber” is an umbrella term for the parts of plants and other foods that your body can’t digest. Your body does not break down fiber. Instead, fiber passes through your system and eases symptoms such as constipation.

It’s important to eat a wide variety of foods instead of relying on one source for fiber intake.

The best way to get fiber without consuming too many calories is to eat high fiber foods. Most vegetables, fruits, and other plant-based foods contain fiber.

If your body is slowly adjusting to more fiber, spread out your portions across multiple meals instead of eating a lot in a single serving.

Fiber is a type of carbohydrate that comes in three main forms: soluble, insoluble, and fermented fiber.

• Soluble fiber dissolves in water and slows down digestion. It can help lower your cholesterol and blood sugar levels.
• Insoluble fiber doesn’t dissolve in water and plays a different role in digestion. It adds bulk to stool and passes through your system more quickly. Basically, it helps keep your pipes working regularly and prevents constipation.
• Fermentable fiber can come from either of the previous two categories, although it is more often soluble fiber. Fermented fiber helps increase the healthy bacteria in your colon.

It’s best to gradually add fiber to the diet. You don’t want to shock your system with too much bulk. “Start low, go slow,” as the International Foundation for Functional Gastrointestinal Disorders puts it.

Here are some tips for adding fiber — but not too much:

• Eat whole fruits such as pears and apples instead of drinking fruit juices.
• Opt for whole grain foods instead of white rice, white bread, and white pasta.
• Snack on vegetables instead of pretzels and chips.
• Eat beans and lentils daily.
• Sprinkle chia seeds on cereal, smoothies, or salads.
• Make sure you’re drinking plenty of water when you eat fibrous food.

You may also find it helpful to track the foods you eat and note the fiber content to better understand how much you’re actually eating. Some people who find it hard to eat enough fiber may want to consider taking a fiber supplement.

That said, too much fiber can also be a bad thing. And your body will speak up (literally and figuratively) with a variety of symptoms if you’re eating too much of it. Fiber supplements have also not been found to be nearly as beneficial as eating high fiber foods.

Keep in mind that everyone’s body reacts to fiber a bit differently. Some people with a condition called irritable bowel syndrome may not tolerate fiber well.

Fiber is also known as “bulk” or “roughage,” and it can make some noise as it passes through your stomach and intestines. While there is no daily upper limit for dietary fiber intake, consuming large amounts may cause discomfort and symptoms such as:

• gas
• bloating
• constipation
• diarrhea
• abdominal cramping

Cut back on your fiber intake if you experience these symptoms and feel that they are the result of your diet and not another condition, like the stomach flu, that has similar symptoms.

If you experience severe symptoms, consult your doctor or visit an urgent care center or the hospital. In rare but serious cases, consuming too much fiber can cause an intestinal (bowel) obstruction, which is a blockage that prevents contents from moving through.
